[WarpScript] reducer.median returns NULL error #393

Hi, Starting from reducer.median the example, and removing one tick from one series as below: ` [ [ NEWGTS "GTS1" RENAME 10 NaN NaN NaN 1 ADDVALUE 20 NaN NaN NaN 5 ADDVALUE

NEWGTS "GTS2" RENAME 
10 NaN NaN NaN 4 ADDVALUE
20 NaN NaN NaN 3 ADDVALUE

NEWGTS "GTS3" RENAME 
10 NaN NaN NaN 3 ADDVALUE
20 NaN NaN NaN 8 ADDVALUE

NEWGTS "GTS4" RENAME 
10 NaN NaN NaN 3 ADDVALUE

] [] reducer.median ] REDUCE `

And then executing the WarpScript returns: ERROR line #18 in section '[TOP]': null
